From the description in Brodo, Physcia adscendens sounds promising.

a perennial purple wallflower, in front yard. Stem perhaps 5 years old, dead, with this one lichen growing on it. Small tubes (<3mm) which may be apothecia-like structures or may just be open-ended tubes also observed. No cilia on reverse, but cilia on lobe tips. Hope Jason has time to look at this.
